In valves for large pipes with a large area made according to this invention it will be found necessary to supply more bearings to support the weight of the valve-sections, because such sections become more numerous with the diameter of the valve. To insure in that case atrue and tight setting of each section upon the other when closing the valve and to support the same while open against derangement on account of their own weight and to hold the same securely against the .ac-Y tion of the fluid passing through the valves, they are supported in the manner shown in Fig. 1. In this case the rod D supports the Valves on one side by resting movably inlthe hub-bearings of the rest Gr and of the valveseat C, and on the other or inlet side of the The operation of the valve is as follows:

When the apparatus has been properly inserted in a pipe-line and the valve is to be opened, the hand-.wheel r is turned in `the direction Open, indicated on the same. The turning of this wheel will by engaging the pinion and gear-wheel with its screw-threaded hub lt move valve stem or' rod D in the direction of the valve-sections, the rest Gr forming the point of resistance, and as the smallest valve-section E is fastened to stem or rod D this valve-section immediately opens, requiring in large-size vvalves seldom more than ive per cent. of the power required to open at one effort the whole of the valve area. When this smallest valve-section has been opened to the desired distance, the collar Z2 will engage the hub f of the valve-section F and push it forward; but as the collar is of a diameter less than that of the valve-port the latter will not be closed and the gas, steam, or liquid will flow around valve E and through valve F to the place of consumption. Each additional section of valve following is equally engaged by a shoulder on the stem or rod D, as before described, but not shown, until the whole area of the valve is opened. For closing the valve the hand-wheel fr is r0- tated in the opposite direction, when the larger sections of the valve will close up lirst and the smallest section last by the backward motion of the valve stem or rod D. The faces of the several sections of valve may be providedv with an elastic medium or otherwise be made to form a tight joint.

rlhe apparatus may be inserted in a pipeline of any desired inclination, with the operating-wheel in any desired position, without affecting its efficiency.

What I claim as new, and wish to secure by Letters Patent, is-

In a valve, the combination of a valve-seat having a guide-bearing, with a threaded valvestem having a collar and engaging the bearing, a rest, a tapped gear-wheelmountcd upon the valve-stem, a pinion engaging the gearwheel, means for rotating the pinion, a slidable rear valve-section adapted to be engaged by the collar, and a front valvesection mounted upon the valve-stem, substantially as specified.

In testimony whereof I have si gned lny n amc to this specification, in the presence of two subscribing witnesses, this 6th day of May, 1903.

FREDERICK WILLIAM A. WlESEBROCK.
